Answer 1

At this time I think you will have to roll your own solution. The same behavior exists with the DJI android mobile sdk. I think the DJI firmware thinks the landing site is not 'safe/even surface' enough to land. If you wanted to roll your own solution then set up a loop to monitor the drone after a return-to-home or landing command is sent. Then if the drone does not land, send a notice to the user to manually land the drone.
